Not only does God have a son
Not only does God have multiple sons
But even those multiple sons have multiple sons
And all of this is within the realm of Heaven, is real, permanent, and always will be.
"This must I accept. For thus am I led past this world to my creations, children of my will, in Heaven where my holy Self abides with them and Him Who has created me."
"Everything God created is like Him. 4 Extension, as undertaken by God, is similar to the inner radiance that the children of the Father inherit from Him. 5 Its real source is internal. 6 This is as true of the Son as of the Father. 7 In this sense the creation includes both the creation of the Son by God, and the Son's creations when his mind is healed. 8 This requires God's endowment of the Son with free will, because all loving creation is freely given in one continuous line, in which all aspects are of the same order."
